Rotary Phase Converters

Before You Buy
There are many phase converters on the market and, provided they are properly sized, most will work well. Unfortunately there are no industry standards that apply to phase converters, so to guarantee you are getting a price on phase converters of identical capacity, you must know the right questions to ask.
Common Phase Converter Issues & Misconceptions
The internet has become the principle source of product information and training for those shopping for a phase converter. Unfortunately, most folks come away from the experience more confused than when they began the research. The reason is that there are simply no industry wide standards that govern the sizing, performance and configuration of phase converters.

HOW A PHASE CONVERTER WORKS

A phase converter is simply a rotating machine, much like a motor, that converts single-phase utility power into 3-phase electricity to operate 3-phase equipment.

What is a Phase Converter
A phase converter is simply a rotating machine, much like a motor, that converts single-phase utility power into 3-phase electricity to operate 3-phase equipment. Phase converters are typically applied where utility 3-phase is unavailable or too expensive to install.
Why Should I Use a Phase Converter
The principle advantage of a phase converter is a matter of economics. Electric utility companies typically charge substantial fees to extend 3-phase service to areas not currently served. Charges vary by terrain, but it is widely accepted that line extension costs range from $30,000 to $90,000 per mile with a common average being $50,000.
The Right Converter for Your Application
A single to three phase converter is the most economical alternative to utility 3-phase. A successful phase converter installation requires knowledge about how each application creates a different type of load, and how these different loads impact 3-phase converter performance. In our 45+ years of experience, Kay Industries has replaced many other brands of failed phase converters.
How Converters are Rated
Phasemaster® Rotary Phase converters are the most conservatively rated phase converters you can buy. To understand why we say this, you need to know a little about frame sizes, and why the frame size is important to rating a phase converter.
